The Fire Magic 3092D is a 1-hour automatic timer gas shut-off valve designed for outdoor grills in commercial and shared-use environments such as hotels, resorts, and vacation clubs. It automatically shuts off gas flow after the pre-set 1-hour limit, helping prevent accidents and reduce energy waste. With a 100,000 BTU flow capacity, it works with both natural gas and propane systems and features ½-inch inlet and outlet connections for easy installation. A 3-hour model is also available (Part #3090).
